Erythrocytes (RBC) were isolated from human blood (EDTA whole blood, collected randomly). 50 ul of the 10% RBC suspension (in PBS) was added to 2 ml of sample solutions (concentration range from 0.1 ug/ml to 400 ug/ml) in PBS. The mixture was vortexed briefly and sat for 60 min at room temperature. The mixture was spun at 3K for 10 min and the relative amounts of lysed hemoglobin in the supernatant were measured at 540 nm. The synthetic compounds of present application were tested with this method.

Acid Hydrolysis of Saponin

15 mg Xanifolia-Y was dissolved in 1 ml of methanol. 1 ml of 2N HCl was then added. The mixture was refluxed in 80 C water bath for 5 hours. The solution was then neutralized by adding 2 ml of 1N NaOH (to final pH 4-6). The aglycone was then extracted with ethylacetate 3 ml×2. The extracts were collected and pooled. Further isolation of aglycone (ACH-Y) was achieved by HPLC with isocratic elution of 80-100% acetonitrile.

C. At the end of the drug-treatment, cytotoxic test was performed with MTT assay.

Conclusion:

-   -   For comparison between cancer cells (ES2) and non-cancerous         cells (WI38), it is found that:

-   1. the IC₅₀ for ES2 cells (0.3 ug/ml) is lower than those of WI38     cells (1.5 ug/ml), and

-   2. The IC₁₀₀ for ES2 cells (0.15-0.3 ug/ml) is lower than those of     WI38 cells (10 ug/ml)

-   3. With 10 ug/ml of Tig-S, about 90% of ES2 cells died while only     10% of WI38 cells died after the drug-treatment.     -   Based on these studies, it is concluded that the fast growing         tumor cells (ES2) are more sensitive to Tig-S than the slow         growing normal cells (WI38).

Experiment 31 Inhibition of Cell Cycling

-   -   1. Method: Cells: Human leukemia cells K562 cultured in RPMI1640         medium.     -   2. Drug: compound from present application or Tig-S (1000× stock         solution in DMSO).     -   3. Start cells concentration: 500000/ml.     -   4. Cells were cultured with drug (0-20 ug/ml) for total of three         days.     -   5. Cells were harvested by centrifugation (136×g, 6 minutes);         fixed with 70% ethanol and kept in −20 C before staining.     -   6. Staining: Fixed cells were stained with Propidium         iodide/RNase A/0.1% Triton X-100 in PBS.     -   7. Flow Cytometry Analysis was performed in Baylor Core Facility         with a LSRII instrument.     -   8. Analysis: Single cell was gated and cell count—FL2-Area         histogram were plotted.     -   9. Cell distribution in different cell-cycle phases (G0/G1, S,         G2/M) was analyzed.

Results:

Cells with no drug, or with 0.15 ug/ml and 0.3 ug/ml of Tig-S, have a similar (same) cell distribution in the G0/G1, S and G2/M phases of cell-cycle. With higher Tig-S concentrations, starting from 0.6 ug/ml, the cells in G2/M phase decrease. The decrease of G2/M cells correlated with higher drug concentrations (up to 20 ug/ml). These results indicate that drug-treated cells were arrested in the S-phase and unable to enter into the G2/M phase of the cell cycle.

Conclusion:

The drug-effect of Tig-S on human leukemia K562 cells is arresting cells in the S-phase and blocking their entering into the G2/M phase of cell cycle. The Compound Tig-S block the DNA synthesis of cancer cell.

Experiment 32 Inhibition of H460 Cells Growth with Tig-S

Methods:

A. Cells

-   -   H460 cells are derived from a Human Lung large cell carcinoma.         Cells were grew in RPMI 1640 medium supplemented with 10% FCS,         antibiotics and glutamine. 5000 cells were seeded in a well         (96-welled plate) for one day before drug-treatment

B. Drug treatment:

-   -   Drug: Tig-S (stored as a 1000× stock solution in DMSO) was used.     -   Drug concentration used: from 0.15-20 ug/ml.     -   Drug-treatment was carried out for 1, 2 and 4 days. For the 4         days incubation, cells were fed with fresh medium (with drug) on         day 2.

C. At the end of the drug-treatment, cytotoxic test was performed with MTT assay.

Results:

1. Tig-S inhibits H460 cells' growth with the IC50 of drug 3 ug/ml.

2. Minimum cells growth inhibition was observed beyond drug 5 ug/ml.

3. No dead cell was found at drug concentration in 20 ug/ml.

The results indicate that Tig-S inhibits the H460 cell's growth, but is not killing cells at high concentrations. Therefore, Tig-S is an effective drug for inhibition of cancer growth but has low toxicity.

Cell distribution in following groups: live, early         apoptosis, late-apoptosis, total apoptosis and dead cells were         determined.     -   15. The percentage of cells in these groups is presented in the         FIG. 19.

Results:

The background apoptosis level of K562 cells (no-drug control) is about 10-15%. After drug-treatment with Tig-S, the apoptotic cells population increased (from 15% to 27%) with increased drug concentration (from 2.5 ug/ml to 20 ug/ml).

Similarly, the dead cell population was also increase with the drug concentration.

Conclusion:

Tig-S induces cell-death by the apoptosis mechanism (not necrosis mechanism).
